They are not the latest CPU controllers results though, some performance results can be downloaded from the following URL. http://prdownloads.sourceforge.net/ckrm/cpurc-v0.3-2615-kernbench.pdf?download http://prdownloads.sourceforge.net/ckrm/cpurc-v0.3-2615-lat_ctx.pdf?download > I'm interested in scenarios with multiple classes in a hierarchy with > varying shares assigned to each class, with one or more cpu hogs in each > class. > > I'm curious to see how well it does in terms of meeting the share targets. The hierarchy is used only to calculate an effective share for each groups in the following manner. The scheduling algorithm treat the groups as if they are defined in a flat level and each of them has its effective share. / effective_min_shares = 100% - 50% - 30% = 20% +---------------+---------------+ /A min_shares=50% /B min_shares=30% effective_min_shares effective_min_shares = 50% - 10% - 25% = 30% - 0% = 15% = 30% +---------------+---------------+ /C min_shares=20% /D min_shares=50% effective_min_shares effective_min_shares = 20% of 50% - 0% = 10% = 50% of 50% - 0 % = 10% = 25% If the min_shares in the resource group /A is changed 50% to 40% in the above example, the effective_min_shares of the resource group /A, /C and /D are automatically changed to 12%, 8% and 20% respectively.
